XR2206 Function Generator Project - Build a cheap, simple function (signal, waveform) generator.
This is not a sponsored project nor did I get the product for free!
See video #97 at https://www.youtube.com/RalphBacon
Here's an uber simple project for generating square waves, sine waves and triangle waves, ideal for general electronics use and for use in Arduino projects too. A simple project like this is also ideal for electronics beginners, with limited soldering skills.

The function (signal) generator kit, here is a link to Amazon but
widely available from the Far Eastern Warehouses too, even cheaper there, but slower delivery of course

CD4093 Quad Dual Input NAND Gate used in the demo as Schmitt trigger

CD4093 for demo purposes is OK but better would be to use a Hex (Six) Single Input Texas Instruments SN74HC14

(see page 3 for the debounce circuit)
(see page 4 for pretty much what I described on converting wave forms)
We'll discuss these ICs in more detail next time we look at this topic.
Here you can read up a bit more about NAND gates
